Abstract
When a detection temperature detected by a refrigerant temperature sensor-is lower than a threshold value, it is determined to be YES at a frosting determining section as an exterior heat exchanger is frosted, an electric control unit reduces an air volume to be blown by an electric blower at an air-volume controlling section. Accordingly, an air volume blown from openings through the heating heat exchanger is reduced. In the result, an air volume passing through the heating heat exchanger can be reduced in a state where the heating heat exchanger heats an inside air using high-temperature high-pressure refrigerant when the exterior heat exchanger is frosted. Accordingly, a temperature of air after passing through the heating heat exchanger can be prevented from decreasing.
